Definitions

  • the present invention relates to a wind deflector according to the preamble of claim 1.
  • the attachment of softer components to the wind deflectors of these two documents has the task of suppressing noise at relevant points such as rattling noises in the region of contact of the wind deflector with the vehicle roof or Windströmungsgehoffsche in the region of a tip of a wind deflector.
  • a disadvantage of the wind deflectors of the prior art on the one hand, that a plurality of individual soft elements must be attached to the wind deflector. This is only possible by means of comparatively complex manufacturing processes.
  • a larger area of the known wind deflector is still rigid and stiff and there must be enough space available to stow the wind deflector without contact in a rest position below the roof outer surface can. It is therefore an object of the present invention to provide a wind deflector, which suppresses the noise even more effective, is easier to produce, and can be pivoted in grazing contact with roof-mounted elements in a rest position and can be stored for reasons of space in partially compressed form.
  • An advantage of a wind deflector according to the invention is that, by having a rigid reinforcing profile, which is enclosed along a substantial portion of its longitudinal extent by a softer molded body forming the outer surface of the wind deflector body, it provides optimum noise suppression.
  • By encapsulating the reinforcing profile with a softer molded body both noise by the inflowing. Air, as well as rattling noises in contact areas between the wind deflector in both extended ' Operational position and effectively suppressed in retracted position.
  • a wind deflector is provided, which is simple and inexpensive to produce, requires little space and optimally suppresses the formation of rattling or wind noise.
  • the reinforcing profile protrudes at the two lateral ends of the Windabweiser emotionss out of the molding and forms at these two ends in each case a fastener by means of which the Windabweiser endeavor at a corresponding movement mechanism, which is preferably coupled to the mechanism for lid movement, is pivotally fastened.
  • the reinforcing profile may also be completely enclosed by the shaped body, in which case separate fastening elements are to be provided on the wind deflector body. These can for example be screwed to the wind deflector, molded or foamed.
  • the molded body preferably consists of rubber or of an elastic polyurethane (PU) foam.
  • the molded body consists of a porous air-permeable material, through which the inflowing air can flow partially through, for example, to suppress the formation of whimpering noises in the vehicle interior.
  • a wind deflector according to the invention can have a net, as they are known, for example, from wind deflectors of Kabriomaleen.
  • a net is secured to the wind deflector body and along the leading edge of the roof opening so as to be stretched over a forming gap between the leading edge of the roof opening and the wind deflector as the wind deflector pivots into the operative position.
  • the net can be foamed or injected onto the edge assigned to the wind deflector into the molded body during its shaping by a foaming or injection process.
  • the network may also be attached to the reinforcing profile.
  • the net is guided within the molding to a projection of the stiffening profile to a non-positive To ensure connection between the network and the reinforcement profile.
  • the network may also be fastened by means of a fastening element in a groove of the molded body, wherein a design as a releasable attachment is possible, so that the network can be easily solved and replaced, for example, in case of damage from the wind deflector.
  • a fastener an element may be provided which is gesp Schwarzt in the groove of the shaped body, such as clamp-like or dowel-like fasteners.
  • the mesh can also be screwed into the groove of the molded body or in the case of shaped bodies without a groove on an outer surface of the molded body, advantageously in the region of the screwing the mesh material has a reinforcement such as an applied reinforcing tape along the net edge.
  • the shaped body has a triangular cross-section, preferably an obliquely formed wind-deflecting front surface and a roof surface substantially parallel base and a vertical rear side forming the triangular shape of the shaped body.
  • the reinforcing profile is formed as a hollow profile.
  • FIGS. 1a to 1d each show a WindabweiserAvem 10 according to the invention, which has an oblique, wind-repellent surface 16 in the direction of travel at the front of Windabweiser endeavor. Since the wind deflector body 10 of the Fig. 1a to 1d each still have a substantially parallel to a roof surface of a vehicle, not shown here, a base surface 18 and a perpendicular thereto rear side 20, the Querterrorismsf kaue the illustrated Windabweiser endeavor 10 is approximately triangular. All WindabweiserAvem 10 of Fig. 1a to 1d each have a reinforcing profile 12 which is embedded in a softer, surrounding the reinforcing profile molding 14.
  • the reinforcing profile 12 the wind deflector body 10 gives a corresponding rigidity
  • the molded body 14 forms the actual outer shape of the wind deflector body 10. So neither in the. Contact the Windabweiser stresses 10 with a roof surface in a flared operating position can still occur with roof-mounted elements in a sunk rest position rattling noises, the reinforcing profile 12 surrounding molding 14 is formed from an elastic material such as rubber or a foam such as a polyurethane foam. To produce this, the reinforcing profile 12 is foamed or overmolded with a corresponding elastic material.
  • the molded body 14 can also be formed so porous that the inflowing air can flow through the molding at least partially to suppress turbulent flow components or at least partially convert it into a laminar flow.
  • the reinforcing profile 12 may further be formed as a hollow profile, such as a tubular profile ( Fig. 1a ) or a hollow profile with outer surfaces parallel to the outer surfaces of the molded body 14 ( Fig. 1d ).
  • a hollow profile as a reinforcing profile and the reinforcing profile 12 may be designed to improve the strength as an approximately H-shaped profile or V-Profd.
  • the Indian Fig. 1d illustrated Windabweiser endeavor 10 further has in the corner region in which meet the wind-deflecting surface 16 and the base 18, a lip 22, which serves to a gap between the issued WindabweiserAvem 10 in the operating position and the adjacent, not shown here front edge of a roof opening at least partially cover, in order to prevent an influx of wind in this gap.
  • the lip 22 is preferably formed directly on the molded body 14 and thus has like this elastic properties, so that it can be pressed against the roof surface, for example under elastic deformation and thereby improves the sealing effect.
  • WindabweiserSystem 10 In contrast to the previously shown Windabweiser endeavorn is on the Wind deflector bodies of Fig. 3a and 3b in each case a Windabweiserianu 10 shown, to which a network 24 is fixed, which at the end remote from the Windabweiseroasa 10 (not shown here) roofproof in the region of a front edge of the roof opening is also fixed.
  • the net 24 is tensioned due to its correspondingly adjusted length and thus covers a gap between the wind deflector body 10 and a front edge of the roof opening, so that only part of the incoming air (coming from the left in the image direction) passes through the net 24 and turbulences within it Air flow can be reduced. This avoids a turbulent influx of wind into the vehicle interior and suppresses careless noises inside the vehicle.
  • the net 24 can be fastened in a groove 26 of the wind deflector body 10, for example with a clamp 28, wherein the clamp is designed such that it spreads out within the groove.
  • the bracket 28 or a similar fastening element can be arranged in the groove 26 so that a detachable connection is formed, so that the network for maintenance or Austauseh of from Windabweiser stresses 10 can be solved again.
  • the net 24 may be as shown in FIG Fig. 3b represented, also be fixedly disposed with its end within the wind deflector body 10 by being enclosed by the molded body 14 at this end, that is, for example, foamed or overmolded.
  • the projection 30 is oriented in this case substantially parallel to the base surface 18, while the longer leg of the approximately V-shaped reinforcing profile 12 is arranged substantially parallel to the front in the direction of travel wind-repellent surface 16.
